To ALL wHoM 1T MAY'CONGERN: t

Be it known that I, W. A. STEVENSON, of Athens, Clarke county, and State of Missouri, have invented aV new and useful Improved Spinning-Machine, of which the following is a full, clear, and exact description, reference being had to the annexed drawing, making a part of this specification, in which- "Figure 1 represents a side elevation of my invention.

Figure 2 represents a transverse sectionof same at :v y.

Figure 3 represents atop viewof one end.

Similar letters indicate like parts.

This machinelis adapted more particularly for family use in spinning yarn.

I t consists of a wooden frame, A, gs. 1, 2, 3, of any desired dimensions, raised to a convenient height, on four standards, a a', g. 1, and d a, fig. 2. The lo'wer part 'of the frame'b b only being shown in iig. 1) serves as a track for the carriage B to travel on. This carriage is made in the common way-,with 4spindles in the part represented by c,and the spindles are connected by bands with the shaft ofthe wheel'd, 'which extends across the carriage from side to side, the wheel d being connected bya-band with the driving-wheel E, which is attached by suitable bearings to the carriage B. l l i v At the opposite end'of the frame is placed a feeding-drum, C, figs. 2, 3,'having a. feeding-belt, D, figs. 1, 3; which also passes over a roller, f, gs. 1, 3, supported by a frame, extending a convenient distance from the end of the mainframe. Inv front of C are placed two jaws, h', iig. 2, extending transversely across the machine, the upper-one moving vertically' in the inverted U-irons g g', figs. 2, 3, and g', g. 1, fastened to the lowrerjaw, while their upper ends are Vconnected byla rod, as shown.` i

To the extremity ofthe shaft of the feeding-drum C is attached a pulley, t', figs. 1, 2,- 3, which is connected by a belt, l`7c, fig. 1, with a like pulley, Z, on the opposite end of the frame.- This belt c is so fastened to the y standard, in which the wheel E has its hearings, as tobe set in moti-on. as the carriage travels back and forth- A rod, e, fig. 1, extending from one end of the frame to the other, has on it a movable stud, m, figs'. 1, 2, which,

slidinglfreely on the rod, may, by means of'a set-screw, be fixed at any desired point.

On the inside'of the pulley z' are placed two ratchet-wheels,1 2, figs. 2, 3,' engaging with one another, the one being attached to the wheel, wlrilethe other moves back and forth on the shaft by means of the lever n, figs. 1, 2,3, which has a stud litting into a groove inf the ratchet 1, in such a vayas not to interfere with its revolving. By means of this lever and its connection, the drum and pulley may be thrown in and out of geur at pleasure. A pivoted bar, o, iig. 3, having one extremity free, is so arranged that when-the ratchets are made t'o engage, a shotilder on the bar prevents the lever from being drawn back bythe spring p, figs. 2, 3. VThe other end of o is connected by a link with the lever g, figs. 1, '3, pivoted on the frame.

On the rod e is firmly fixed a lever, r, gs. 1., 2, connected 4by a rod with the step s, figs. 2, 3, pivoted on the underjaw-i, and connected )Vith a spiral spring, as shown. The lever 1 has an arm, 4, figs. 1, 2, 3, which engages with'g. The upper jaw'is connected by leversititig. 1, tt', figs.- 2, 3, with levers 4v', iig. 1,`and v e', fig.. 2. i `When-the machine is tobe used, the carriage is pushed against the levers v v', which raise theljaw 71. until the plate w, figs. 2, 3, risingfabove the step s, allows thespring o2 to actand draw the step under it, thus holding the jaw up. When the carriage is pushed against the levers ce', a prpjeetion on the standard supporting the wheel E acts upon the lever n, causing the ratchets to engage. The wool is drawn through between the jaws, and is attached to spindles in the usual way, and the carriage is drawn back the operator at the same' time, with one hand, turns the wheel E, while the feeder splices the wool on the feeding-belt as fast as necessary.4 The helt and drum are made to revolve by the motion of the carriage. The stud m is placed as far from the jaws as is necessary to give a given length of roving, and the cam u,'on the carriage, strikes it as the carl riage passes out, and causes'the rod vto-make'a partial revolution, drawing the step s back, and causing the jawI to fall and hold the yarn tight, allowing no more to pnss through. The same movement of the rod also causes the ratchets to ungear, by raising the lever g by the arm 4, which lifts the lever rt, allowing the springp to act.

.The yarn noivbeing held firmly by the jaws, and the feeding-drum no longer revolving, it may be twisted I and stretched as much as desired; and then by moving the carriage towards the jaws, the yarn may be Wound' up, and, and thejaws being again raised and the drum thrown into gear, the operation may be repeated. The jaw may be made heavy enough to fall by its own weight, or be provided with a spring, z, fig. 2.

This machine requires but two to work it--one to feed and the other to Work the earriage-all its other operations being automatic, by reason of its peeuliar arrangement of-levers, 82e. This obvintes the necessity of one ofthe operators stopping each time to raise and lower the jan', or throw the feeding-shaft in or out of gear.

I do'not claim any novelty in the construction ofthe carriage or its spindles and belting, nor in the use of thejaws, feedingfdrum, belt, and roller described, since these are similar to those ordinarily used in spinningrnaehines of this kind', but

What I do claim as my invention, and desire to secure by Letters Patent, is-' 1. The `rod e, stud m, levers 7', v v', lantl t t', jaws h L, step s, and plate w of a 'spinningmachinm nll constructed, arranged, and operating in relation to one another and the other pnrtsof the machine, substantially as andfor the purpos'e speeiied.v A

2. The rod e, stud m, lever r and its arm 4, levers n and q, with its connections, ratchets 1 2 of a spinningmachine, all constructed, arranged, and operating relatively to themselves and the other parts of the machine, as and for the purpose speciied. I i' 3. The combination of the parts above mentioned with the' frame A, carriage B, drum C, belt D, and roller fof a spinning-machine,'as and for the purpose-specified.
